After information about location parameters of a camera is obtained in this paper, the virtual model is rendered into real scenes with OpenGL to realize virtual-real fusion. The experimental results suggest that it costs short time to process complicated natural images with the algorithm proposed in this paper. In case of any illumination change, scale change, rotation in scenes, it is adaptable to complex outdoor environment, showing relatively high timeliness and robustness.","PeriodicalId":424212,"journal":{"name":"4th International Conference on Smart and Sustainable City (ICSSC 2017)","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121424638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The machine vision technique applied in the self-driving car can facilitate the car detecting and tracking other vehicles, pedestrians, lanes and traffic signs on the road, etc. This paper proposed an algorithm to track the vehicle with the adaptively changed scale. First, we use the tracker to obtain the vehicle candidates at each frame based on kernelized correlation filter. Next, an array of particles was created to represent different scales. Further, a new image feature representation based on integrated-color-histogram was proposed to insert the updated scheme concerning the particle filter algorithm. Last, we used one smooth method to make the scales change have its own memory to prevent it from violent variation. In the experiment section, we have chosen some pervasive tracker to analyze. The results showed that in the aspects of both accuracy and robustness, our proposed algorithm worked more properly compared with the other algorithm, by virtue of its minimal error relative to the data benchmark.","PeriodicalId":424212,"journal":{"name":"4th International Conference on Smart and Sustainable City (ICSSC 2017)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132524280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Shi, Hongtao Chen","doi":"10.1049/CP.2017.0118","DOIUrl":"https://doi.org/10.1049/CP.2017.0118","url":null,"abstract":"Wireless sensor networks (WSNs) used in distributed surveillance commonly requires network-wide time synchronization. Most existing time synchronization protocols assume that the clock with each node can be modeled by a linear equation at + b with t being the universal time, a the clock drift (skew) coefficient, and b the clock offset. Some protocols assume that a = 1, hence the synchronization target is the parameter b while others assume that a could deviate from one and both parameters a and b are the synchronization targets. In the latter case algorithmic synchronization details become complicated, requiring either involved computation or memory use. For example, the recently proposed Average TimeSync (ATS) protocol demands expensive use of memory within each WSN node. In this work a memory-lite time synchronization (MLTS) protocol is proposed, which can achieve synchronization of both drift and offset just by sending synchronization packet including the past time stamps received by the sender node, but the number of such past stamps is minor. Both simulation and hardware experimental results justify that the proposed memory-lite protocol is still capable of effective distributive time synchronization with robustness but at the slight price of a little slowed down synchronization speed.","PeriodicalId":424212,"journal":{"name":"4th International Conference on Smart and Sustainable City (ICSSC 2017)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114546581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a novel approach for quantity forecast of administrative data which is named after parallel random forest (parallel RF). Firstly, we collect administrative data from different online systems using java program and store it in MongoDB. Then we extract key information from these data and assign different numbers to different administrative areas and item names. Next, as the core of whole method, we train the prediction model by implementing the random forest method on Hadoop Map-Reduce. Finally, we compare the execution efficiency and prediction accuracy with other standard algorithms such as SVM and gradient boosting. The experiment shows that the accuracy and efficiency of our method is much better than other algorithms and our method is more reliable and useful.","PeriodicalId":424212,"journal":{"name":"4th International Conference on Smart and Sustainable City (ICSSC 2017)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125774430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
